Sam Brown begins to close gap with incumbent Sen. Jacky Rosen in battleground Nevada

Ret. Army Capt. Sam Brown appears to be closing the polling gap with incumbent Democratic Sen. Jacky Rosen in battleground Nevada with less than two weeks until Election Day. 

In a new survey, Rosen defeated Brown 49% to 44% among all voters, according to a new AARP poll. 

Among the key demographic of voters 50 years or older, Brown beat the Democrat 49% to 46%.

The new poll, which indicates a close race, comes after some expressed concerns over the Republican's position behind Rosen in recent surveys. While many Republican candidates in crucial states had already improved their stature against incumbent Democrats, Brown was still losing to Rosen by significant margins. 

In a late August poll from CNN, Rosen was leading Brown by a full 10 points, 50% to 40%. In a Fox News Poll during the same month, the Democrat beat her opponent by even more, 55% to his 41%. 

Earlier in the month, a New York Times and Siena College Poll had Rosen besting Brown 49% to 40%.
